Ameer Hamza Z.

AI developer for business owners. I build AI chatbots that answer your customers from your own prices and policies, automations that take admin off your team, and I add AI to the website or app you already run. I'm a Microsoft certified developer with 8+ years of experience. I've built software for Fortune 500 companies and for growing businesses in US health-tech, fintech and e-commerce. What I build • AI chatbots and assistants. They answer your customers on your website or app using your own prices, services and policies, and hand the conversation to you when it needs a person. • AI in your existing app or website. Search that understands questions, reading and sorting documents, drafting replies, summaries and reports, added to the system you already use. • Automations for repetitive work. For example, a new enquiry comes in, it goes into your CRM, the customer gets a reply and your team gets a task. I build these with n8n, Windmill or custom code. • Private AI on your own data. I fine-tune open-source models on your documents and past conversations and test them on my own GPU workstation. The finished model runs on your server or your cloud, so your data stays with you. • AI agents for your team. Agents that draft quotes, summarise calls, sort emails or pull reports, with a person approving the important steps. • Websites, web applications and mobile apps. Business websites, booking systems, client portals, dashboards and online stores, plus Flutter mobile apps and Electron desktop apps. Who this is for Clinics, contractors, property managers, consultants, shops and other small and growing businesses. For example: a chatbot on a clinic's website that answers booking questions after hours, quote requests from a contractor's website going straight into the CRM with a reply sent, or a client portal so customers stop emailing for updates. Recent work • US health-tech: I built the AI assistant inside a live wellness app. It gives each user personal answers at any time of day, with safety checks built in. • Fintech: senior engineer on an international money-transfer platform, working on the systems behind sending money, payments and customer accounts. • Education: an online course platform for a training academy, live with real students, with locked lessons, instalment payments and progress tracking. • E-commerce: online stores for a UK boutique and a kids' clothing brand, built so the owners can run them without a developer. Why clients work with me • One person for the whole job. I build the AI, the app, the database and the server setup, so you don't have to manage three freelancers. • AI that is already live. The assistant I built runs in a live app with real users, so I know what goes wrong after launch and how to fix it. • 8+ years as a senior engineer on software that handles real payments and health data. • Flexible hours. I work with clients in the US, UK, Europe and Australia and make time for calls in your working day.
